Rehabilitation of Exenterated Right Eye: A Prosthetic Challenge

Background: Facial defects can be acquired or congenital, but irrespective of etiology, any maxillofacial structure if damaged or missing will result in an unaesthetic and unappealing personality of individual. Orbital defects are very evident and effect the appearance and social front of the individual. Many modalities are available to rehabilitate the defect of an orbit but prosthetic rehabilitation with silicone prosthesis is a simple and effective approach. Retention is generally achieved by engaging available undercuts or using mechanical accessories or skin adhesives etc. This case report describes successful rehabilitation of right orbital defect using a non-surgical approach with room temperature vulcanized silicone and skin adhesives. Case Report: A 45 yr old male reported with, chief complaint of missing right orbit and unaesthetic appearance secondary to gunshot wound. Patient was not ready for any more surgical procedures or additional accessories and available retentive undercuts were minimal. Hence, conventional silicone prosthesis was made using stock eye shell and room temperature vulcanized silicone retained with skin adhesives. The approach was simple to a complex problem and gave reliable result in very limited time. Conclusion: With extensive orbital defect, rehabilitation is difficult and complex as retention is compromised and it is difficult to match the shade of the prosthesis.This case represents a simple and predictable approach to a case of exenterated right orbit with conventional roomtemperature vulcanized silicone and silicone skin adhesives.

Combination of skin flap and silicone prosthesis for rehabilitation of a large orbital defect: A case report

Exenteration surgery greatly affects a person in terms of function, esthetics, and psychological trauma. In such cases, restoration by silicone orbital prosthesis is a well-accepted treatment option. However, this is a difficult task, necessitating personalized design of method for each patient. This case report describes the technique for fabrication of a silicone orbital prosthesis for a male patient with left orbital defect due to exenteration of a Grade 3 squamous cell carcinoma of the left eye and surrounding tissues. The patient was delivered with a satisfactory silicone orbital prosthesis having good retention and finish. Multidisciplinary management and team approach are crucial in providing precise and effective rehabilitation for improving the patient's quality of life and help them return to their normal social life.

Rehabilitation of orbital defect with silicone orbital prosthesis retained by dental implants.

Orbital defects can result from cancer, birth anomalies, or trauma leading to an onslaught of problems in the function and psyche of the patient. These defects are restored by surgical reconstruction and followed by placement of orbital prosthesis for cosmetic makeup. The use of dental implants in retaining orbital prosthesis improves patient acceptance of the prosthesis owing to better retention and stability than conventional adhesive retained prosthesis. This case report describes a custom‑made magnetic retentive assembly anchored by a dental implant which offers the orbital prosthesis the simplicity of self‑alignment and ease of use.

Use of Anatomical Undercut in Adhesive Retained Orbital Prosthesis: An Alternative to Osseointegration to Improve Retention and Reduce Margin Gap.

Introduction: Poor retention, stability and margin gap due to excessive bone lose following surgery is one of the major problems of rehabilitation in orbital defect with adhesive retained orbital prosthesis. Presentation of Case: This clinical report describes a simplified technique for the fabrication of an adhesive retained silicone orbital prosthesis by proper evaluation and using of remaining tissue undercuts to achieve ideal fit and aesthetics in a patient who has severely loss orbital bone after the surgery. Discussion: Aesthetics will be compromised if the proper evaluation of remaining tissue and treatment plan is not done prior prosthetic rehabilitation. To solve this issue sometimes maxillofacial prosthodontist may have to think for implant retained facial prosthesis. This is also sometime not possible due to several factors such as peri-implantitis, hygiene practice and dose of radiation etc. Conclusion: Proper use of remaining anatomical undercuts can be an alternative way to overcome the issue.

Prosthetic rehabilitation after orbital exenteration: A case series.

Orbital exenteration is executed by the ophthalmic surgeon to treat various neoplasms or non-malignant diseases. But it leads to several functional, esthetic and psychological problems for the patients. Orbital prosthesis is a good alternative for cosmetic and psychological rehabilitation, if reconstructive surgery is not possible or not desired by the patient. In the following article, diff erent materials and retentive aids for fabrication of an orbital prosthesis given in the literature along with few novel methods have been discussed for four patients who underwent orbital exenteration. Factors that an ophthalmic surgeon should consider during surgery, which may later on help the prosthodontist to obtain good cosmetic results, are also discussed briefly. Remarkable results can be obtained if both work as a team for one common goal i.e. improvement of quality of life of the patient after orbital exenteration.

A modified technique for retention of orbital prosthesis.

An orbital defect (congenital or acquired) causes severe facial asymmetry and disfigurement, which results in psychological and social disturbances to the patient. It becomes a challenging task for a maxillofacial prosthodontist to fabricate a prosthesis that replicates the healthy side of the face. Success of the prosthesis depends primarily on satisfactory retention of the same. This clinical report illustrates rehabilitation of a patient with an orbital defect by fabricating a hollow orbital prosthesis, utilizing anatomical undercuts for retention using an acrylic resin template relined by a resilient denture liner.
